Battery replacement.

I keep em clean , use dielectric grease on the terminals and in 2 years they're gone .

 

All of them go away ...i abuse my batteries tho with an inverter .

 

A group of batteries is only as good as the weakest one. Unless the batteries are only a month or 2 old and one was defective, I'd say change them all.

 

A service call will buy ya 4 new batteries ...junk batteries arnt worth screwing with and they will take out an alternator.

 

What are you doing? What are you really asking?
One truck running the road change them all. Local yocal or have a 6 month old battery fail maybe just one.
Like to put batteries in otr trucks in sets and good used batteries together in the dogs and city trucks.

 

400 bucks every 2 years is worth the peace of mind to me .

 

A few months back my trk had battery "issues ".
2 were junk , thee other 2 had a little life left .
Replaced 2 , ended up replacing thee other two a month later .
Lesson learned ~ when one goes thee others arent far behind , save a trip to the shop and have them all replaced.
Note ~ batteries were 3 + years old so not a total surprise .
